A-Frames are the only things I have done with them (when using them by themselves) but that's enough to justify carrying one for me. I'm not trying to make any space blanket wilderness mansions or anything. Just something to provide a little shade during the day and maybe keep the ticks from landing on me as they fall out of the trees while I sleep in the summer and something to keep me dry and/or reflect heat in the winter. That being said, I agree there are better options. My preference is the Storm Shelter Instant Pocket Tent but often enough is the space blanket that goes with me do to is light weight and extreme compactness.
